..and don't miss the movie Mike made. Click the "V"on that Unclog dialogue box.
See it now before it goes to Blu Ray or Red Box.

This afternoon I wondered where they were in the unclog image :-) Hitting the peak pulse values per ink channel still depends on the K partitioning done in the media presets, the neutral spine can even be split on 4 inks: MK, PK, Gray and Light Gray ink. Similar for LC am LM. Red, Green and Blue ink channels depend on hue angle and saturation in best case, like on the HP Z3200/Z3100. If available the Red, Green and Blue inks do not all have the same hue for different brands. Gloss Enhancer channel is a separate issue.

Usually the Matte Art Paper media presets have the highest ink load. PK not taking part then in most cases.

Both the movie and instructions say about using Letter size paper. That is not generally available in the UK (or Europe) so is it OK to use A4 paper. I notice that the pattern shrinks to the width (short dimension) of the A4 paper and leaves white spaces top & bottom of the page.

Hue of the ink is not relevant.  We don't care if a few dots from other colors get mixed in.  The only thing we need for this pattern to work is for most of the ink to come from the selected color and that it is pulsed at the prescribed rates.  I've actually checked the dot patterns under high magnification and on these patterns, hue angle has to be off by more than 20 degrees to make a significant impact on the pulsing pattern of the nozzles of any given color: so just sending the general hues for the primaries is fine.

A4 is fine as I thought that was your letter size "over there".  What do you write letters on anyway?  ;)  But it looks like you did find a bug.  The chart isn't supposed to get truncated.  It looks like that bug crept in when I changed the pattern in the last couple versions.  Well, I haven't released two versions in a day in a long time so I'd better get to work.  :P
